I just ordered the 24-70 II from Newegg. They had four in stock when I ordered, so as of this post, they should still have three left.
They seem to be the only company in the USA that has current stock, and got VERY lucky with a brainstorm to take a look at NewEgg.... not generally thought of for photo equipment. I confirmed the stock with online chat and should have the lens by Friday latest.
If you've been looking to buy, I'd go IMMEDIATELY to NewEgg and see if the 24-70 page still shows stock.
Price same as everywhere else... $2299.00
